Evaluation of Oxidative Dehydrogenation Catalysis

Oxidative dehydrogenation (ODH) is an important process for converting ethane or propane into more valuable ethylene or propylene. Ethylene has a specific IR absorption band around 950 cm4, which has been utilized by two research groups, using IR-based gas sensors, in the HTS of ethane ODH. Cong et al. at Symyx have used photothermal deflection [12, 13] and Johann et al. at the Max Planck Institute used a PAS sensor [24]. Johann et al. reported that position-sensi- 

Ethane ODH catalysis by mixed oxides of nickel and iron has been evaluated by both the gas sensor and an FID gas chromatograph. Fig. 8.11(a) shows the C2H4
